Couplings
Hangzhou Chinabase Machinery Co., Ltd. supplies industrial couplings including HRC, NM, MH, and flexible jaw types, designed for torque transmission in rotating machinery. The couplings are manufactured to standard dimensions with bore diameters ranging from 6 mm to 120 mm, and are available in cast iron, steel, and aluminum housings depending on load requirements. All products are machined to ISO 9001 tolerances for concentricity and runout, with keyway and set-screw options for shaft retention.
Typical materials include GGG40 ductile iron for high-torque applications and AL6061 for lighter-duty uses where corrosion resistance is needed. Nylon sleeve couplings feature polyamide inserts with a torque rating up to 150 Nm and operate within a temperature range of -20°C to 80°C. Standard surface treatments include black oxide or zinc plating for corrosion protection, though custom finishes are available upon request. These are not consumer-grade components but engineered for industrial environments with vibration and misalignment.
These couplings are used in conveyor systems, pumps, fans, and packaging machinery across food processing, agriculture, and light manufacturing. Buyers include OEMs, maintenance departments, and mechanical integrators sourcing direct from manufacturers. Trade terms typically include FOB Hangzhou or CIF port of destination, with minimum order quantities starting at 10 pieces per model. Packaging is in corrugated cartons with foam inserts, and custom labeling is supported for bulk shipments.

Sourcing Couplings from Hangzhou Chinabase Machinery Co., Ltd. - China Import Guide
Before placing an order, verify the exact coupling type and material grade with the supplier using the product code or drawing reference. Confirm bore size, keyway dimensions, and torque rating match your shaft and motor specifications. Request a sample for fit and function testing if this is your first purchase. Do not rely on generic product names like 'flexible coupling' without technical drawings.
Confirm Incoterms with the supplier - FOB Hangzhou is standard, but CIF or DAP may be available. Lead time for standard items is typically 10 to 15 days; custom orders take 3 to 4 weeks. Payment terms are usually 30% advance, 70% before shipment. Ask for a packing list and commercial invoice that lists each coupling model, quantity, and serial batch number.
Inspect shipments for physical damage and verify that packaging includes manufacturer labels and batch codes. Check for rust or surface defects on metal components. Request a material certification (EN 10204 3.1) if using stainless or high-strength alloys. For critical applications, consider third-party inspection for dimensional accuracy and torque test validation before release.
